ABSTRACT:
Aspects of the present invention provide apparatuses and methods for conducting pupil height measurements. A multifocal measurement device of the present invention can comprise a base member and first and second adjustable measurement members. The multifocal measurement device can be connected to eyeglasses worn by a patient. A first knob can be used to adjust a vertical positioning of the first adjustable measurement member and a second knob can be used to adjust a vertical positioning of the second adjustable measurement member. The adjustable measurement members can each comprise pupillary alignment reference areas—such as transparent lines, opaque lines, or prisms—that can be positioned substantially in front of the pupils of the patient by adjusting the knobs. Pupil height measurements can subsequently be made by measuring the distances between the first and second pupillary alignment reference areas and the bottom of the eyeglasses worn by the patient.
